I found this Piano at a fleemarket. What i made, is what is inside. It consist of an arduinoboard, 12 solenoids (electromagnets) and some mechanical devices constructed out of pianowire. Learn more about Arduino here arduino.cc

This is one solution for Goodiepals Mort Aux Vaches Ekstra Extra, that me and Voks worked out together. It is a 2 oscillator analog synthesizer and a sequencer with 3 seperate timelines. We have also made a second book related to this one, but i do not have any pictures of that.
